3D object converter could succesfully open and convert it for me, but it's going to take a while to texture the whole thing since textures have to be manually placed. The XR-2 Ravenstar on the other hand didn't work, when you try to open it in 3D object converter it looks like this

Added (09.03.2014, 17:00)---------------------------------------------EDIT : The XR-5 Vanguard mesh seems to work, however the lots of textures are misplaced on it. (here is what it looks like now). I'm not going to release it in my thread, but if you still want it PM me.

You should've just ported the ships from Mass Effect rather than editing dontpanic's old addon. Looking through the files it really seems like you made cheapish emis maps. His ships were highly modified and edited to work with 0.9.6 and lacked support for newer features in 0.9.7.1

Ignoring the red color and a few minor things. Here is the Normandy ported to SE 0.9.7.1 properly by HarbingerDawn

As you can see the Normandy has lights, as do many of the other ships you didn't add an emis for.

Protip: Don't release ships unless they're actually at release quality and take full advantage of everything the new version has to offer.
